Fask Facts -The Association of American Physicians and Surgeons

A curated list of mask facts and medical publications.

COVID-19 is as politically-charged as it is infectious. Early in the COVID-19 pandemic, the WHO, the CDC and NIH’s Dr. Anthony Fauci discouraged wearing masks as not useful for non-health care workers. Now they recommend wearing cloth face coverings in public settings where other social distancing measures are hard to do (e.g., grocery stores and pharmacies). The recommendation was published without a single scientific paper or other information provided to support that cloth masks actually provide any respiratory protection. Let’s look at the data.

  • Surgical masks are loose fitting. They are designed to protect the patient from the doctors’ respiratory droplets.  There wearer is not protected from others’ airborne particles.
  • People do not wear masks properly. Many people have the mask under the nose. The wearer does not have glasses on and the eyes are a portal of entry.  If the virus lands on the conjunctiva, tears will wash it into the nasopharynx.
  • Most studies cannot separate out hand hygiene.
  • The designer masks and scarves offer minimal protection. They give a false sense of security to both the wearer and those around the wearer.
    **Not to mention they add a perverse lightheartedness to the situation.
  • If you are walking alone, no need for a mask. Avoid other folks; use common sense.
  • Remember: children under 2 years should not wear masks because of accidental suffocation and difficulty breathing in some.
  • Even if a universal mask mandate were imposed, several studies noted that folks do not use the mask properly and over-report their wearing.  Additionally, how would the mandate be enforced??
  • The positive studies are models that assume universality and full compliance.
  • If wearing a mask makes people go out and get Vitamin D – go for it. In the 1918 flu pandemic people who went outside did better.  Early reports are showing people with COVID-19 with low Vitamin D do worse than those with normal levels. Perhaps that is why shut-ins do so poorly.

Prof. Carl Heneghan On Masks

https://youtube.com/watch?v=QNI2ocgosgA
  • Masks and gloves have been shown in studies to help in the medical setting but not in the home setting.
  • Cloth masks are worse and may increase infection.
  • Masks in the UK were supposed to reduce infections by 40% but in fact, infections went up.
  • Study in Norway: 200,000 people would have to wear a mask in order to prevent one infection. Public health impact of mask wearing is negligible.
  • This advocating mask-wearing have cherry-picked low-quality observational evidence to suit the evidence.

‘Mask Mouth’ is Smelly Side Effect of Mask Wearing – Dr. Rob Ramondi, California Globe

California Globe has seen reports of lung infections from long-term mask wearing, persistent coughing, as well as dermatitis on the skin around the mouth.

Providing one more reason healthy people should not wear face masks, Dentists report they are seeing a new syndrome brought about by mask-wearing which the doctors have dubbed “mask mouth,” Fox News reports.

The moisture trapped in face masks creates a petri dish of breeding ground for bacteria, as it is  in place directly over your mouth.

Constant mask-wearing “is leading to all kinds of dental disasters like decaying teeth, receding gum lines and seriously sour breath.

“We’re seeing inflammation in people’s gums that have been healthy forever, and cavities in people who have never had them before,” says Dr. Rob Ramondi, a dentist and co-founder of One Manhattan Dental. “About 50% of our patients are being impacted by this, [so] we decided to name it ‘mask mouth’ — after ‘meth mouth.’ ”

Man, 26, suffers collapsed lung after jogging 2.5 miles while wearing face mask – The Mirror

A young man fell to the ground due to a collapsed lung after running two-and-a-half miles while wearing a face mask.

Doctors say his condition was caused by the high pressure on the man’s organ, due to his intense breathing while wearing the face covering…

Doctors say Mr Zhang had a spontaneous pneumothorax, which are more likely to occur with people who have asthma, cystic fibrosis or pneumonia.

Preliminary report on surgical mask induced deoxygenation during major surgery – PubMed (2008)

Abstract
Objectives: This study was undertaken to evaluate whether the surgeons’ oxygen saturation of hemoglobin was affected by the surgical mask or not during major operations.

Methods: Repeated measures, longitudinal and prospective observational study was performed on 53 surgeons using a pulse oximeter pre and postoperatively.

Results: Our study revealed a decrease in the oxygen saturation of arterial pulsations (SpO2) and a slight increase in pulse rates compared to preoperative values in all surgeon groups. The decrease was more prominent in the surgeons aged over 35.

Conclusions: Considering our findings, pulse rates of the surgeon’s increase and SpO2 decrease after the first hour. This early change in SpO2 may be either due to the facial mask or the operational stress. Since a very small decrease in saturation at this level, reflects a large decrease in PaO2, our findings may have a clinical value for the health workers and the surgeons.

Contamination by respiratory viruses on outer surface of medical masks used by hospital healthcare workers – BMC Infectious Diseases

Background
Medical masks are commonly used in health care settings to protect healthcare workers (HCWs) from respiratory and other infections. Airborne respiratory pathogens may settle on the surface of used masks layers, resulting in contamination. The main aim of this study was to study the presence of viruses on the surface of medical masks.

Methods
Two pilot studies in laboratory and clinical settings were carried out to determine the areas of masks likely to contain maximum viral particles. A laboratory study using a mannequin and fluorescent spray showed maximum particles concentrated on upper right, middle and left sections of the medical masks. These findings were confirmed through a small clinical study. The main study was then conducted in high-risk wards of three selected hospitals in Beijing China. Participants (n = 148) were asked to wear medical masks for a shift (6–8 h) or as long as they could tolerate. Used samples of medical masks were tested for presence of respiratory viruses in upper sections of the medical masks, in line with the pilot studies.

Results
Overall virus positivity rate was 10.1% (15/148). Commonly isolated viruses from masks samples were adenovirus (n = 7), bocavirus (n = 2), respiratory syncytial virus (n = 2) and influenza virus (n = 2). Virus positivity was significantly higher in masks samples worn for > 6 h (14.1%, 14/99 versus 1.2%, 1/49, OR 7.9, 95% CI 1.01–61.99) and in samples used by participants who examined > 25 patients per day (16.9%, 12/71 versus 3.9%, 3/77, OR 5.02, 95% CI 1.35–18.60). Most of the participants (83.8%, 124/148) reported at least one problem associated with mask use. Commonly reported problems were pressure on face (16.9%, 25/148), breathing difficulty (12.2%, 18/148), discomfort (9.5% 14/148), trouble communicating with the patient (7.4%, 11/148) and headache (6.1%, 9/148).

Conclusion
Respiratory pathogens on the outer surface of the used medical masks may result in self-contamination. The risk is higher with longer duration of mask use (> 6 h) and with higher rates of clinical contact. Protocols on duration of mask use should specify a maximum time of continuous use, and should consider guidance in high contact settings. Viruses were isolated from the upper sections of around 10% samples, but other sections of masks may also be contaminated. HCWs should be aware of these risks in order to protect themselves and people around them.

“Exercise with facemask; Are we handling a devil’s sword?” – A physiological hypothesis – NCBI

Straying away from a sedentary lifestyle is essential, especially in these troubled times of a global pandemic to reverse the ill effects associated with the health risks as mentioned earlier. In the view of anticipated effects on immune system and prevention against influenza and Covid-19, globally moderate to vigorous exercises are advocated wearing protective equipment such as facemasks. Though WHO supports facemasks only for Covid-19 patients, healthy “social exercisers” too exercise strenuously with customized facemasks or N95 which hypothesized to pose more significant health risks and tax various physiological systems especially pulmonary, circulatory and immune systems. Exercising with facemasks may reduce available Oxygen and increase air trapping preventing substantial carbon dioxide exchange. The hypercapnic hypoxia may potentially increase acidic environment, cardiac overload, anaerobic metabolism and renal overload, which may substantially aggravate the underlying pathology of established chronic diseases. Further contrary to the earlier thought, no evidence exists to claim the facemasks during exercise offer additional protection from the droplet transfer of the virus. Hence, we recommend social distancing is better than facemasks during exercise and optimal utilization rather than exploitation of facemasks during exercise.

Coronavirus: Face masks could increase risk of infection, medical chief warns – Independent

Members of the public could be putting themselves more at risk from contracting coronavirus by wearing face masks, one of England’s most senior doctors has warned.

Jenny Harries, deputy chief medical officer, said the masks could “actually trap the virus” and cause the person wearing it to breathe it in.

“For the average member of the public walking down a street, it is not a good idea” to wear a face mask in the hope of preventing infection, she added.

 Jake Dunning, head of emerging infections and zoonoses [infectious disease spread between humans and animals] at Public Health England, told The Independent there was “very little evidence of a widespread benefit” from wearing them.

Masks Don’t Work: A review of science relevant to COVID-19 social policy – ResearchGate

Masks and respirators do not work. There have been extensive randomized controlled trial (RCT) studies, and meta-analysis reviews of RCT studies, which all show that masks and respirators do not work to prevent respiratory influenza-like illnesses, or respiratory illnesses believed to be transmitted by droplets and aerosol particles. Furthermore, the relevant known physics and biology, which I review, are such that masks and respirators should not work. It would be a paradox if masks and respirators worked, given what we know about viral respiratory diseases: The main transmission path is long-residence-time aerosol particles (< 2.5 μm), which are too fine to be blocked, and the minimum-infective-dose is smaller than one aerosol particle. The present paper about masks illustrates the degree to which governments, the mainstream media, and institutional propagandists can decide to operate in a science vacuum, or select only incomplete science that serves their interests. Such recklessness is also certainly the case with the current global lockdown of over 1 billion people, an unprecedented experiment in medical and political history.

Why is Sweden not recommending face masks to the public?

Face masks in public spaces do not provide any greater protection to the population,” Johan Carlson from the Swedish Public Health Agency Folkhälsomyndigheten said at a press conference on May 13th.

Swedish health authorities argue that keeping a distance, washing your hands, not touching your face, and staying at home if you experience any symptoms are still the best ways to halt the spread of the coronavirus. There is a concern that wearing face masks would make people follow these guidelines less strictly.

  • There is a risk of a false sense of security.
  • The virus can gather in the mask and when you take it off, the virus can be transferred to your hands and thereby spread further.
  • Worn properly, masks might reduce the spread of infection if worn by those with asymptomatic infections, even if they might not protect the wearer themselves.

Face Masks Pose Serious Risks To The Healthy – Russell Blaylock MD

As for the scientific support for the use of face mask, a recent careful examination of the literature, in which 17 of the best studies were analyzed, concluded that, “ None of the studies established a conclusive relationship between mask/respirator use and protection against influenza infection.”1

When a person is infected with a respiratory virus, they will expel some of the virus with each breath. If they are wearing a mask, especially an N95 mask or other tightly fitting mask, they will be constantly rebreathing the viruses, raising the concentration of the virus in the lungs and the nasal passages. We know that people who have the worst reactions to the coronavirus have the highest concentrations of the virus early on. And this leads to the deadly cytokine storm in a selected number.

Respiratory consequences of N95-type Mask usage in pregnant healthcare workers—a controlled clinical study – Antimicrobial Resistance and Infection Control (2015)

Results
Exercising at 3 MET while breathing through N95-mask materials reduced mean tidal volume (TV) by 23.0 % (95 % CI −33.5 % to −10.5 %, p < 0.001) and lowered minute ventilation (VE) by 25.8 % (95 % CI −34.2 % to −15.8 %, p < 0.001), with no significant change in breathing frequency compared to breathing ambient air. Volumes of oxygen consumption (VO2) and carbon dioxide expired (VCO2) were also significantly reduced; VO2 by 13.8 % (95 % CI −24.2 % to −3 %, p = 0.013) and VCO2 by 17.7 %, (95 % CI −28.1 % to −8.6 %, p = 0.001). Although no changes in the inspired oxygen and carbon dioxide concentrations were demonstrated, breathing through N95-mask materials during low intensity work (3 MET) reduced expired oxygen concentration by 3.2 % (95 % CI: −4.1 % to −2.2 %, p < 0.001), and increased expired carbon dioxide by 8.9 % (95 % CI: 6.9 % to 13.1 %; p <0.001) suggesting an increase in metabolism. There were however no changes in the maternal and fetal heart rates, finger-tip capillary lactate levels and oxygen saturation and rating of perceived exertion at the work intensity investigated.

Conclusions
Breathing through N95 mask materials have been shown to impede gaseous exchange and impose an additional workload on the metabolic system of pregnant healthcare workers, and this needs to be taken into consideration in guidelines for respirator use. The benefits of using N95 mask to prevent serious emerging infectious diseases should be weighed against potential respiratory consequences associated with extended N95 respirator usage.

Effect of a surgical mask on six minute walking distance – PubMed (2017)

Results: Distance was not modified by the mask (P=0.99). Dyspnea variation was significantly higher with surgical mask (+5.6 vs. +4.6; P<0.001) and the difference was clinically relevant. No difference was found for the variation of other parameters.

Conclusion: Wearing a surgical mask modifies significantly and clinically dyspnea without influencing walked distance.

The physiological impact of wearing an N95 mask during hemodialysis as a precaution against SARS in patients with end-stage renal disease – PubMed (2004)

Results: Thirty nine patients (23 men; mean age, 57.2 years) were recruited for participation in the study. Seventy percent of the patients showed a reduction in partial pressure of oxygen (PaO2), and 19% developed various degrees of hypoxemia. Wearing an N95 mask significantly reduced the PaO2 level (101.7 +/- 12.6 to 92.7 +/- 15.8 mm Hg, p = 0.006), increased the respiratory rate (16.8 +/- 2.8 to 18.8 +/- 2.7/min, p < 0.001), and increased the occurrence of chest discomfort (3 to 11 patients, p = 0.014) and respiratory distress (1 to 17 patients, p < 0.001). Baseline PaO2 level was the only significant predictor of the magnitude of PaO2 reduction (p < 0.001).

Conclusion: Wearing an N95 mask for 4 hours during HD significantly reduced PaO2 and increased respiratory adverse effects in ESRD patients.

Pakistan accused of cover-up over fresh polio outbreak – The Guardian (2019)

From Thu 7 Nov 2019:

After the strand was eliminated from Pakistan five years ago, all P2 vaccines should have been collected from hospitals and clinics and not used. However, it appears a P2 vaccine was administered accidentally and a child became a carrier for the disease. Tests on the new cases allegedly show the children are all carrying a vaccine-derived form of the disease .

…However, it is understood that, instead of publicly declaring the renewed outbreak and beginning a public vaccination campaign, a “secret” vaccination campaign will begin on Monday in Rawalpindi and surrounding cities in an attempt at containment.

Ministers lose fight to stop payouts over swine flu jab narcolepsy cases – The Guardian

Dozens of British children who developed narcolepsy as a result of a swine flu vaccine could be compensated after the high court rejected a government appeal to withhold payments.

Six million people in Britain, and more across Europe, were given the Pandemrix vaccine made by GlaxoSmithKline during the 2009-10 swine flu pandemic, but the jab was withdrawn after doctors noticed a sharp rise in narcolepsy among those who received it.
